Weekly Quiz Competition

Question 1
1 / -0

Represent $$1.2380, 1.2379, 2.3567, 1.2375$$ on a number line and state which is smallest.

A
$$1.2380$$

B
$$1.2379$$

C
$$2.3567$$

D
$$1.2375$$

Solution

Smallest number is $$1.2375$$
So, option D is correct.
Question 2
1 / -0

Represent $$1.2380, 1.2379, 1.3567, 1.2375$$ on a number line and state which is greatest.

A
$$1.2380$$

B
$$1.2379$$

C
$$1.3567$$

D
$$1.2375$$

Solution

Greatest number is $$1.3567$$
So, option C is correct.
Question 3
1 / -0

Which decimal number does the arrow represent?

A
$$6.380$$

B
$$6.378$$

C
$$6.375$$

D
$$6.374$$

Solution

Let the point $$6.37$$ is marked as $$A$$ and $$6.38$$ is marked as $$B$$
Length $$AB=6.38-6.37=.01$$
Number of units between $$A$$ and $$B$$ $$=10$$
Length of each unit $$=\dfrac{.01}{10}=.001$$
Given point is $$8$$ units forward from $$6.37$$
So, the location of given point $$=6.37+.001\times8=6.378$$.
Hence, option B is correct.
Question 4
1 / -0

Co-ordinate of $$P$$ is :

A
$$2.1$$

B
$$2.2$$

C
$$2.3$$

D
$$2.4$$

Solution

$$\textbf{Step 1: Using number line}$$
$$\text{It can be seen that between two whole numbers there are 5 divisions}$$
$$\Rightarrow \text{1 division}=\dfrac15$$
$$\text{It can be seen that P is after 1 division after 2}$$
$$\Rightarrow \text{Coordinate of P}=2+1\times\dfrac15=2.2$$
$$\textbf{Hence , the coordinate of the point P is }\mathbf{2.2}$$ $$\textbf{Option B is correct.}$$
Question 5
1 / -0

Simplify:
$$417.25 - 41.72 - 4.53 =$$ ?

A
$$380.06$$

B
$$371$$

C
$$348$$

D
$$315$$

E
None of these

Solution

$$417.25 - 41.72 - 4.53$$
$$=371$$.
Hence the correct answer is option B
Question 6
1 / -0

Convert $$2.387$$ kg into grams.

A
$$2.387$$ g

B
$$23.87$$ g

C
$$238.7$$ g

D
$$2387$$ g

Solution

$$1\ \ kg=1000\ \ g\\ 2.387\ \ kg=2.387\times 1000=2387\ \ g$$
So option $$D$$ is correct
Question 7
1 / -0

Fill in the banks:
$$88 cm = $$ _____ $$ meter $$

A
$$0.88$$

B
$$0.66$$

C
$$0.55$$

D
$$0.99$$

Solution

$$1$$ meter $$= 100$$ cm

So, $$88 \, cm =$$ $$\dfrac{88}{100} \, meter$$

$$= 0.88$$ meter
Question 8
1 / -0

$$5.8377\ kg=$$ _______ $$g$$

A
$$5837.7\ g$$

B
$$583.77\ g$$

C
$$58.377\ g$$

D
$$58377\ g$$

Solution

$$1\ \ kg=1000\ \ g$$
$$5.8377\ \ kg=5.8377\times1000=5837.7 \ \ g$$
So option $$A$$ is correct.
Question 9
1 / -0

Fill in the banks:
$$7\, kg\, 250\, grams$$ = ______ $$kg$$

A
$$7.250$$

B
$$7.75$$

C
$$7$$

D
$$7.35$$

Solution

$$1$$ kg $$= 1000$$ gm

So, $$7$$ kg $$250$$ gm = $$7$$ kg $$+ 250$$ gm

$$= 7$$ kg + $$\dfrac{250}{1000}$$ kg

$$= 7$$ kg $$+ 0.250$$ kg

$$= 7.250$$ kg
Question 10
1 / -0

Convert $$0.05$$ kg into grams.

A
$$0.5\ g$$

B
$$5\ g$$

C
$$50\ g$$

D
$$500\ g$$

Solution

$$1\ \ kg=1000\ \ g$$
$$0.05\ \ kg =0.05\times1000=50\ \ g$$
So option $$B$$ is correct.
